The clarinet induced black hole.
Although I have never seen it myself, I am certain that my children's school has its own black hole, a dark region from which even light cannot escape. Because whenever my kids re-enter the school after 3 p.m., they seem to disappear. And my children are forever returning to the building for a drink of water, a trip to the bathroom, a forgotten backpack, a missing pencil sharpener.
Each time, they seem to disappear for a long, long time. Five minutes, 10, 15... Once, they disappeared for a half-hour. When they emerged, I asked what the heck they'd been doing inside.
I got a shrug and "I dunno."
The Hole was the only explanation I could fathom.
The Hole struck again a few weeks ago as I was picking up my children from school. My older daughter's butt had barely touched the car seat before she leaped from the vehicle. "I forgot my clarinet in my locker!" she yelped.
She jogged into the building. And that's when the Hole got her.
